This paper examines the problem of constructing integrated information security systems, specifically organizing the information interactions between their modules. To support a well-founded selection of the most effective organization for such interactions, a corresponding evaluation methodology is proposed, presented both schematically (from the perspective of an expert and a computing tool) and analytically. The methodology is based on graphical modeling of the integrated security system in terms of the interactions between its modules, enabling the calculation of absolute performance indicators. Using the same indicators for an «ideal» system, specific indicators are determined, suitable for direct comparison and the calculation of the integrated performance value. Based on the authors' previous research, methods for implementing these steps are proposed. The novelty of the methodology, its theoretical and practical significance, and potential future research are highlighted.
